摘要： PROBLEM TO BE SOLVED: To suppress hunting of an expansion valve without impairing durability of a compressor. SOLUTION: Inclination of the control characteristic EV of the expansion valve 131 is larger than that of the saturated vapor pressure curve of a circulation refrigerant R134a in a refrigerating cycle in a temperature-pressure diagram. The control characteristic EV intersects with the saturated vapor pressure curve of the circulation refrigerant R134a at high load temperature. The control characteristic EV is so set that when evaporation temperature is in a low temperature area, a superheat degree SH is reduced as the evaporation temperature is raised. The control characteristic EV is so set that when the evaporation temperature is in a high temperature area, dryness DN is reduced as the evaporation temperature is raised. As a result, even if an internal heat exchanger 160 is provided, it is possible to suppress temperature rise of the inlet refrigerant of the compressor 110 in the high temperature area and to avoid hunting operation of the expansion valve 131 in the low temperature area.

摘要翻译：要解决的问题：抑制膨胀阀的振荡而不损害压缩机的耐久性。解决方案：在温度压力图的制冷循环中，膨胀阀131的控制特性EV的倾斜大于循环制冷剂R134a的饱和蒸汽压力曲线的倾斜。控制特性EV与循环制冷剂R134a在高负载温度下的饱和蒸气压曲线相交。控制特性EV设定为当蒸发温度处于低温区域时，随着蒸发温度升高，过热度SH减小。控制特性EV设定为当蒸发温度处于高温区域时，随着蒸发温度升高，干燥度DN降低。结果，即使设置有内部热交换器160，也可以抑制高温区域内的压缩机110的入口制冷剂的温度升高，并且能够避免膨胀阀131在低温区域的振荡。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To suppress a combustion type heater to frequently repeats stopping and operation.
SOLUTION: A controlling water temperature for stopping a combustion type heater is switched based on the revolution speed of an engine. Thereby, when the revolution speed of the engine is reduced to get to the eco-run state, since the controlling water temperature for stopping the combustion type heater gets to, for example, 80°C-85°C, even if a flow rate of hot water circulating through the heater is reduced and the temperature of hot water circulating through the heater gets to 80°C or higher, the combustion type heater 20 is not stopped until the temperature of hot water gets to 85°C or higher. Accordingly, it can be suppressed that the combustion type heater 20 frequently repeats stopping and operation, for example, as compared with the case where the controlling water temperature is fixed to 80°C not depending on the revolution speed of the engine when the combustion type heater 20 is stopped.

摘要翻译：要解决的问题：抑制燃烧式加热器频繁地重复停止和操作。解决方案：基于发动机的转速来切换用于停止燃烧式加热器的控制水温。因此，当发动机的转速降低到生态运行状态时，由于用于停止燃烧式加热器的控制水温达到例如80℃〜85℃，所以即使流量通过加热器循环的热水的温度降低，并且通过加热器循环的热水的温度达到80℃以上，直到热水的温度达到85℃以上，燃烧式加热器20才停止。因此，可以抑制燃烧式加热器20例如与控制水温度固定为80℃的情况相比，频繁地重复停止和运转，而不依赖于发动机的转速，当燃烧型加热器20停止。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To attain both the restraint of an increase in compressor driving power and assurance of a heat regenerating amount by condensed water of an evaporator in a heat regenerating type vehicle air conditioner. SOLUTION: This air conditioner is so formed that, in operating a compressor 1, setting may be switched between an ordinary mode of controlling the temperature of the evaporator 9 at such a level that the condensed water is not frozen and a heat regerating mode of controlling the temperature of the evaporator 9 at a level below freezing temperature, so that the condensed water is frozen and, in both the ordinary mode and the heat regenerating mode, the restarting target temperature for restarting the compressor 1 may be set so as to be higher by a prescribed value than the stopping target value for stopping the compressor 1, thereby setting a maximum hysteresis width of a difference between the stopping target temperature and the restating target temperature smaller in the heat regenerating mode than in the ordinary mode.

摘要： PROBLEM TO BE SOLVED: To improve cooling feeling of an occupant by gear ratio control corresponding to a degree of cooling request of an air conditioner. SOLUTION: The inside of a cabin is cooled by an evaporator 9 of a refrigerating cycle R having a compressor 1 driven by a vehicle engine 4. This transmission control device includes a transmission 24 for automatically controlling gear ratio (Ni/No) of input rotation speed Ni to output rotation speed No continuously or in multi-stages depending on an operation state of a vehicle, and increases rotation speed of a vehicle engine 4 by correction of the gear ratio (Ni/No) when a degree of cooling request as in cool down just after starting the cooling. Thus, rotation speed of the compressor 1 is increased to improve cool down performance.

摘要： PROBLEM TO BE SOLVED: To provide heat exchanger layout pursuing space efficiency and to reduce frosting on a case of an air-conditioning unit. SOLUTION: An evaporator 21 is disposed almost horizontally in a case so as to form a space on the lower side of the evaporator 21. The case below the lower side surface of the evaporator 21 is provided with a condensed water drain pipe 21c for draining condensed water produced at the evaporator 21. When the condensed water flows down and drains from the condensed water drain pipe 21c, the falling condensed water is heated by high temperature blast air before cooling, so that the outer surface temperature of the case is not lowered much. Frosting on the case is therefore reduced considerably or eliminated, so that an insulator (heat insulating material) to be mounted inside the case can be disused to further reduce cost.

摘要： PROBLEM TO BE SOLVED: To improve transmittable torque and to improve the quality of a magnetic joint while restraining a cost increase by forming a clearance between an inner peripheral wall of both plates composed of a cross-sectional U-shaped magnetic material and an outer peripheral wall of a magnet. SOLUTION: A driven side magnet member 105 is constituted by forming a clearance δ2 between an inner peripheral wall of a driven side plate 105b and an outer peripheral wall of a first permanent magnet 105a. While, a driving side magnet member 106 is fixed to a motor shaft 51 at a prescribed interval from the driven side magnet member 105 by sandwiching a partition wall member 9 composed of a nonmagnetic substance, and in this driving side magnet member 106, a clearance δ3 is formed between an inner peripheral wall of a driving side plate 106b and an outer peripheral wall of a second permanent magnet 106a. At this time, a cost increase is restrained by obviating grinding work of an outer peripheral surface of the permanent magnets 105a and 106a by constituting a magnetic circuit between both magnet members 105 and 106 by using both plates 105b and 106b composed of a cross-sectional U-shaped magnetic material.

摘要： PROBLEM TO BE SOLVED: To absorb sliding by an elastic member even if centers of driving shaft and a fan shaft are slid from each other, and improve reliability of a battery cooling blower by providing a hook type joint for transmitting turning force of a first hook means to a second hook means through the elastic member. SOLUTION: In an electric vehicle including a hybrid vehicle, a centrifugal multiplied fan rotatively driven by a fan shaft 4 is rotatively driven by an electric motor through hook joint 15, and thereby, a secondary battery in a casing is cooled. The hook joint 15 is formed in such a constitution that an elastic member 15c is push-pressed by the hook means 15a fixed to a joint shaft 16, and thereby, turning force is transmitted to the hook means 15b fixed to the fan shaft 4 through the elastic member 15c. It is thus possible to absorb that centers of the joint shaft 16 and the fan shaft 4 are slid from each other, and it is also possible to improve reliability of the hook joint 15 since shearing force is not acted on the elastic member 15c.
